AI Technical Summary
In existing technologies, the boron-asphalt multiphase system has poor compatibility. After high-temperature polymerization, the non-metallic elements decompose and volatilize, and cannot be retained in the asphalt system, resulting in poor oxidative crosslinking and mixing processes, which affects production efficiency and material performance stability.
Design a production device for easily graphitized coating materials, including an additive silo, a mixed solvent silo, a catalyst silo, an asphalt silo, a blending solvent mixer, a pressurized reactor, a liquid phase coating tank, a hypergravity reactor, a molecular distillation apparatus, a scrubbing tower, an RTO furnace, and a crusher. This device enables automatic feeding of raw materials, online blending, and precise temperature control of the reaction. The pressurized reactor and hypergravity reactor help retain the additives from decomposition.
It achieves efficient mixing and precise temperature control, improving production efficiency. The produced coating material has excellent conductivity and cycle stability, making it suitable for the large-scale production of lithium battery anode materials.
